Two cases are really simple: we (i.e. the python interpreter) and the

layout of the structures matches up and all is well.
When we are 64 bit and the target process is 32 bit we need to use
custom 32 bit versions of the structures.
When we are 32 bit and the target process is 64 bit we need to use
custom 64 bit version of the structures. Also we need to use separate
Wow64 functions to get the information.
A few helper structs are defined above so that the compiler can handle
calculating the correct offsets.

typically functions implemented in C which forgot to free() memory
from the heap. It does so by checking whether the process memory
usage increased before and after calling the function many times.
Note that this is hard (probably impossible) to do reliably, due
to how the OS handles memory, the GC and so on (memory can even
decrease!). In order to avoid false positives, in case of failure
(mem > 0) we retry the test for up to 5 times, increasing call
repetitions each time. If the memory keeps increasing then it's a
failure.
If available (Linux, OSX, Windows), USS memory is used for comparison,
since it's supposed to be more precise, see:
https://gmpy.dev/blog/2016/real-process-memory-and-environ-in-python
If not, RSS memory is used. mallinfo() on Linux and _heapwalk() on
Windows may give even more precision, but at the moment are not
implemented.
PyPy appears to be completely unstable for this framework, probably
because of its JIT, so tests on PYPY are skipped.

Tests for detecting function memory leaks (typically the ones
implemented in C). It does so by calling a function many times and
checking whether process memory usage keeps increasing between
calls or over time.
Note that this may produce false positives (especially on Windows
for some reason).
PyPy appears to be completely unstable for this framework, probably
because of how its JIT handles memory, so tests are skipped.

======================================
Starting from version 5.3.0 psutil adds unicode support, see:
https://github.com/giampaolo/psutil/issues/1040
The notes below apply to *any* API returning a string such as
process exe(), cwd() or username():
* all strings are encoded by using the OS filesystem encoding
(sys.getfilesystemencoding()) which varies depending on the platform
(e.g. "UTF-8" on macOS, "mbcs" on Win)
* no API call is supposed to crash with UnicodeDecodeError
* instead, in case of badly encoded data returned by the OS, the
following error handlers are used to replace the corrupted characters in
the string:
* Python 3: sys.getfilesystemencodeerrors() (PY 3.6+) or
"surrogatescape" on POSIX and "replace" on Windows
* Python 2: "replace"
* on Python 2 all APIs return bytes (str type), never unicode
* on Python 2, you can go back to unicode by doing:
>>> unicode(p.exe(), sys.getdefaultencoding(), errors="replace")
For a detailed explanation of how psutil handles unicode see #1040.
Tests
=====
List of APIs returning or dealing with a string:
('not tested' means they are not tested to deal with non-ASCII strings):
* Process.cmdline()
* Process.connections('unix')
* Process.cwd()
* Process.environ()
* Process.exe()
* Process.memory_maps()
* Process.name()
* Process.open_files()
* Process.username() (not tested)
* disk_io_counters() (not tested)
* disk_partitions() (not tested)
* disk_usage(str)
* net_connections('unix')
* net_if_addrs() (not tested)
* net_if_stats() (not tested)
* net_io_counters() (not tested)
* sensors_fans() (not tested)
* sensors_temperatures() (not tested)
* users() (not tested)
* WindowsService.binpath() (not tested)
* WindowsService.description() (not tested)
* WindowsService.display_name() (not tested)
* WindowsService.name() (not tested)
* WindowsService.status() (not tested)
* WindowsService.username() (not tested)
In here we create a unicode path with a funky non-ASCII name and (where
possible) make psutil return it back (e.g. on name(), exe(), open_files(),
etc.) and make sure that:
* psutil never crashes with UnicodeDecodeError
* the returned path matches

Show detailed memory usage about all (querable) processes.
Processes are sorted by their "USS" (Unique Set Size) memory, which is
probably the most representative metric for determining how much memory
is actually being used by a process.
This is similar to "smem" cmdline utility on Linux:

Checks for broken links in file names specified as command line
parameters.
There are a ton of a solutions available for validating URLs in string
using regex, but less for searching, of which very few are accurate.
This snippet is intended to just do the required work, and avoid
complexities. Django Validator has pretty good regex for validation,
but we have to find urls instead of validating them (REFERENCES [7]).
There's always room for improvement.
Method:
* Match URLs using regex (REFERENCES [1]])
* Some URLs need to be fixed, as they have < (or) > due to inefficient
regex.
* Remove duplicates (because regex is not 100% efficient as of now).
* Check validity of URL, using HEAD request. (HEAD to save bandwidth)
Uses requests module for others are painful to use. REFERENCES[9]
Handles redirects, http, https, ftp as well.
REFERENCES:
Using [1] with some modifications for including ftp

About
=====
psutil (process and system utilities) is a cross-platform library for \
retrieving information on running processes and system utilization (CPU, \
memory, disks, network) in Python. It is useful mainly for system \
monitoring, profiling and limiting process resources and management of \
running processes. It implements many functionalities offered by command \
line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, \
nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It \
currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, \
NetBSD and AIX, both 32-bit and 64-bit architectures. Supported Python \
versions are 2.7 and 3.4+. PyPy is also known to work.

ffhq-features-dataset | ffhq-features-dataset-master/README.md | ## Gender, Age, and Emotions extracted for Flickr-Faces-HQ Dataset (FFHQ)
This dataset provides various information for each face in the Flickr-Faces-HQ (FFHQ) image dataset of human faces.
The dataset consists of 70,000 json files, each corresponding to a face. For each face, it contains some of the following information:
* head pose
* gender
* age
* moustache, beard, and sideburns probability
* glasses
* emotion: anger/contempt/disgust/fear/happiness/neutral/sadness/surprise
* blur level
* exposure
* noise level
* eye makeup and lip makeup
* accessories
* occlusion
* hair: bald/invisible/hair color probabilities
* smile probability
* face bounding rectangle
## Overview
Information on downloading the images is available on the [FFHQ official page](https://github.com/NVlabs/ffhq-dataset). The extracted features are inside the json folder of this repository.
For example, `00000.json` contains the following information:
```
